摘　　要：针对不同林分保健功能的差异,提出林分保健功能分析方法,为今后森林保健和森林康养的建设规划与管理提供科学依据。选取广东省佛山市云勇森林公园中阴香Cinnamomum burmannii林,灰木莲Magnolia blumei林,湿地松Pinus elliottii林,黧蒴锥Castanopsis fissa林,尾叶桉Eucalyptus urophylla林和阔叶混交林等6种林分,在10:00-16:00森林保健旅游高峰期,分析体感舒适程度等级、空气离子指数、空气颗粒物质量浓度和植物精气相对含量等4个指标,开展林分保健功能的综合评价研究。结果显示:6种林分的体感舒适程度等级总体上均处在"舒适"及以上水平;6种林分的空气离子指数等级总体上处在Ⅲ级和Ⅳ级水平,具有一定的保健作用;6种林分的细颗粒物(PM_(2.5))和总悬浮颗粒物(TSP)总体上处在一级质量浓度限值范围内,湿地松林、黧蒴锥林、尾叶桉林和阔叶混交林的可吸入颗粒物(PM_(10))均超过了一级质量浓度限值;6种林分所释放的植物精气物质相对含量均较低,其中阴香林释放5种(相对含量为8.15%),灰木莲林释放3种(3.01%),湿地松林释放4种(3.92%),尾叶桉林释放3种(2.91%),黧蒴锥林释放4种物质(7.99%),阔叶混交林释放3种(1.91%);综合评判,阴香林和黧蒴锥林的综合保健功能在6种林分中表现最佳。林分内的相对湿度对体感舒适度和空气颗粒物质量浓度均有影响,发挥森林保健功能需充分关注林分内相对湿度的最优阈值。云勇森林公园旅游更适宜出行的时间为10:00-14:00。通过模拟植物自然状态下释放到林分空气中的植物精气相对含量较低,需考虑有利于植物精气类物质积累的森林小环境营建与林分结构配置。In order to evaluate the differences of health care functions among different forest stands, a method for analyzing forest health function was put forward, which provides a scientific basis for the planning and management of forest health care and forest conservation in the future. The 6 forest stands were selected in Yunyong Forest Park, Foshan City, Guangdong Province, including Cinnamomum burmannii, Magnolia blumei, Pinus elliottii, Eucalyptus urophylla, Castanopsis fissa and broadleaf stands, to analyse human comfort index, air ion index, atmospheric particulate matter and the phytoncidere between 10：00 and 16：00 for the forest health care function evaluation. The results showed the human comfort grade in the 6 forest stands were generally at the grade of Comfortable and Very Comfortable; the air ion index grade of the 6 forest stands were all at the level of grade Ⅲ and Ⅳ, and had certain health effects; The PM_（2.5） and TSP of the 6 forest stands were in the range of the first concentration limit, and PM10 of P. elliottii, C. fissa, E.robusta and broadleaf stands exceeded the first-order concentration limit. Phytoncidere released from the 6 forest stands was low： the C. burmannii released of 5 kinds（8.15%）, M. blumei released of 3 kinds（3.01%）, P. elliottii released of 4 kinds（3.92%）,E. robusta released of 3 kinds（2.91%）, C. fissa released of 4 kinds（7.99%）, and broadleaf stands released of3 kinds（1.91%）; Integrated with the human comfort grade, air ion index, PM_（2.5）, and the phytoncidere, C. burmannii and C. fissa stands were evaluated as the best health care function of all the 6 forest stands in Yunyong Forest Park. The relative humidity in the forest stand has an effect on both the human comfort index and the atmospheric particulate matter, which indicated that to play the function of forest health, close attention should be paid to the relative humidity of the forest stand. The suitable time to visit Yunyong Forest Park is between10： 00-14： 00. Because of
